The advent of wearable technology has brought with it a pressing need for energy storage solutions that can keep pace with the flexibility and stretchability of soft electronic devices. Conventional rigid batteries and supercapacitors have proven inadequate for seamless integration into wearables that must conform to the human body and withstand the strain of daily use. This mismatch between energy storage and device flexibility has hindered progress in fields such as health monitoring, smart textiles, and biomedical implants.
